Strip Punctuation From Field

[Curtis Wilde]

>From all I've read, using something like PatternReplaceFilterFactory allows
you to replace / remove text in an index, but is there anything similar that
allows manipulation of the text in the associated field? For example, if I
pulled a status from Twitter like, "Hi, this is a #hashtag." I would like to
remove the "#" from that string and use it for both the index, and also the
field value that is returned from a query, i.e., "Hi, this is a hashtag".
